The latter orfinger-pieces 11, and theirfulcrum portions can be made longitudinally movable or set are formed bythe inverted-V portions 10. for case-shifting or bringing different rowsof Each key-lever can thus be readily made to type to the printing-line.The rock-sleeve or 0 mount or straddle its respective fulcrum or tubulardriving-shaft 22 is shown mounted 9o block 7, 8, or 9. The riser 4has anupwardlyon a stud 28 and can be held from slipping extending combportion,teeth or cuts of which off by a suitable nut. The sleeve 29 andstud serve as a front guide for the various sets of 28 are carried byframe 30, which can rock or key-levers. The rear guide for thekey-ietilt on shaft 16. This frame or hearing 30 .5 vers is shown at theriser 5. carries a bracket 35, supporting a slidable 5 A shaft 16 formsa support for swinging rack36,havingastop-arm,orrathertwoarms, arms 17,of which two are shown on opposite 39 extended forwardly or toward therow of sides of the median line; but the description pins 18. This rackis engaged by a gearof one arm with its operation explains the wheel 37,rotating with the type-wheel or its 56 other. Shaft 16 is preferablyformed of two sleeve 29. Springs 38, hitched to a suitable "too point,say a bar 18, tend to return or hold the type raised or away from theplaten and return the driving-levers 19. The rack-race 35 is shown withan arm or segment 44, Fig. 2, and a locking-bail 43 engages this arm tolock the type wheel against tilting toward the platen. When a key-leveris struck, it raises its corresponding pin 18 and swings crossbar 18with the respective arm 19 to rotate the driving-sleeve 22 withshoulder-piece 21 and rotate segment 24 and type-wheel 1, the gear-wheel37 rotating with such type-wheel. This gear-wheel slides rack 36 withstop 39 until the latter is arrested by the pin 18,

raised by the actuated key. Rotation of the type-wheel is now stopped.The pin 18 contin uing to press onto bar 18 and the key-lever havinglifted the locking-bail 43 out of hook 44, the frame 30 is tilted tobring the typewheel to the platen for a printing stroke, the tubularshaft 22 and rack-race 35 rocking with the frame.

The spacing arrangement maybe of any suit-able kind. In the drawings isindicated the well-known dog 46, with rack 47 on the carriage of roller2, the dog being actuated by arm or bail 50 at escapement-shaft 51 andengaged by or extended over the key-levers. By omitting a pin 18 thecorresponding keylever becomes a spacer and will actuate the feed-dog,but not the type-wheel.

The ribbon or inking device is not shown, as any suitable in k-rollerwill do.

The case-shift movement of wheel-shaft 27 can be done by a lever-arm 55,Fig. 2, fulcrumed at 56 and having an arm 58, Fig. 1, engaged by orreaching over one or more shift-keys. The keys thus act directly on theshift-lever, so that the construction is simple.

Secured to a suitable part of the machine is an arm 48', Fig. 2, andwhen the type-wheel is printing the toothed disk 48 engages this arm orborn 48, Fig. 7, to further lock the type-wheel to insure accuracy.

The levers 19 when at rest or in normal position rest against screws orstops on frame 30, and a stop 66, Fig. 2, limits the upward swing of thetype-wheel-that is to say, the backward swing of arm 41. These stops arepractically made adjustable for obvious reasons.

The type-wheel shaft and the driving-shaft 22 are shown at an angle toone another, the type wheel being in convenient striking position to theplaten and the driving-shaft having its arm 23 extended toward suchtypewheel shaft.

As seen in Fig. 5, the driving-levers 19 when at rest hold theshoulder-piece or slotted bracket 21 in what may be called centralposition or in the position from which the shoulder-piece is to startrotating to the right or to the left. In other words, the piece 21 is.made to extend rearwardly, by which means either of theoppositely-located driving-levers both on its driving and returnmovement will positively drive and positively return the shoulder-pieceor contacting part 21, with which said levers contact, and whichcontacting-piece moves the type-wheel-driving gear or segment 24 or therotating member 23, carrying said segment, and which segment is curvedor centered about the center 28, about which member 23 rotates. Thepivoted key-levers, having their inner ends or the pins 18 of said innerends arranged under the forward ends or bars 18 of the levers 19, are inconvenient position to swing said levers to strike shoulder 20. Thetypewheel-carrying sleeve 29 being mounted on the rear upper part ofshaft 27 allows play to the latter and to the lever 55 forcase-shifting, and the rack-driving gear at the front of this sleeve 29is in convenient position for the application of rack 36.
